Weak high pressure will move into the region today bringing with it breezy and chilly conditions. Low pressure will move from the southeastern states tomorrow to the Mid-Atlantic coastline near southeastern Virginia by later tomorrow night. The air will only be moderately cold for this system; consequently, precipitation should begin here in the form of rain during the afternoon hours. However, once the low scoots by to the coast and our winds shift to a more northerly direction, colder air will move in and the rain will mix with sleet and snow and then change to all snow tomorrow night. Accumulations are possible by later tomorrow night primarily to the N and W of the District where 1-2 inches could fall. Moderate cold weather continues on Thursday and Friday, but then colder air plunges into the eastern states this weekend, and that cold air outbreak could be accompanied by some steady snow or just snow showers. More on that weekend threat as the week progresses.
